Improvement in pumps



UNITED STATES PATENT OFFICE@ KEARAN REED, OF NEW YORK, N. Y. t

IIVIPROi/Elvn-:NT -IN PUMPS.

Specification forming part'of Letters Patent No. 52,446, dated February 6, 1866.

To all lwhom it may concern:

Beit known that L KEARAN REED, of the city and county and State of New York, have invented certain new and useful Improvements in the Manufacture of Pumps; and I do hereby declare the following to be a full, clear, and exact description of the same,l reference being had to the annexed drawings, making part of this specification, in which- Figure l is a vertical longitudinal section, showing the interior construction of said improvements. Fig. 2 is an end elevation of a pump lconstructed upon my plan, showing the pump-rods connected to the pumpingbeam; and Fig. 3, a top view of such a pump with the beam and connectingrods left off.

This invention consists in a novel method ot' constructing a pump, by which greater facility is afforded for taking it apart to repair it and great compactness and efficiency are united in one pump.

The following description of my invention will enable any one skilled in the arts to which it appertains to make and use the same.

In manufacturing pumps upon my plan, I first construct a chest or chamber, A, of the general form and proportion shown on the drawings, or it may be made of such other form and proportion as will meet the taste or judgment ofthe constructing engineer. Under the bottom of this chamber I make the receiving-channel and nozzle B C, the channel being represented by B and the nozzle by C. Upon the bottom of said chests I construct seats for the pump-cylinders by making circular anges a a large enough to receive the bottom anges of the cylinders. rIhese seats are arranged in the chest, as indicated in the drawings, and through their respective centers holes are cut, over which receiving-valves I) D are placed, as shown in the drawings. These valves, consisting of the ordinary flap variety, are cut out of leather and tted with metal plates in the usual way. They are made large enough in diameter to t the seats of the pump-cylinder under which they are placed, and by which they are secured when said cylinders are adjusted for use. Upon the upper end of each of said cylinders, and on the outside thereof, there are three lugs orbosses, b b, A

made to form bearings for acorrespondin g number of set-screws, c c, which are made to pass through an internal flange, d, formed around the upper edge of the chest A. By means of these set-screws the pump-cylinders and recei vin g-valves are both secured in their places.

Having thus constructed, adjusted, and secured the chest-cylinders and receivingvalves', I proceed to construct the pum p-cover, which is shown in the drawings by E, and which in one piece comprises at once a cover for the pumpchamber, a support for the beam F,and an air-chamber (shown by H) which reaches down between the cylinders in the manner shown. Now this cover forms a tightjoint on the chest A and is secured by four set-screws or bolts, two of which are shown by ff, so that to expose the entire interior of the pump it is only necessary to take out these four screws and lift olf the cover, which carries with it the pump-buckets, connections and all, by which the operator gains access to any and every part of the pump, and by simply loosening the set-screws c the cylinders and lower valves may be removed, thus disuniting in a very brief' space of time all the various parts of the pump, and thus affording the greatest possible facilityfor cleaning, repairing, and readjusting.

It will be seen that there is nothing new in the principle of this pump; tnat the invention consists of an improvement in the method ot' manufacturing the pump, increasing its simplicity and compactness without in any way impairing its efficiency.

What I claim, therefore, as my invention, and desire to secure by Letters Patent, is-

A new article of manufacture consisting of a pump comprising the Water-chamber A A, as shown, the two pump-cylinders K K, secured and arranged within said chamber, as shown, and the air chamber H, made, arranged, and secured over said Water-chamber and said pump-cylinders, as shown and described.
